Answer:

7.900 cm

Step-by-step explanation:

The computation of the diameter after using the tape is given below:

Since the circumference is 14.8 cm

And it would be decrease by 2.4 cm

So, the new circumference is

= 14.8 - 2.4

= 12.4 cm

Now the radius is

= 12.4 ÷ π

= 3.95

And, the diameter is

= 3.95 × 2

= 7.900 cm

a winery has a vat with two pipes leading to it. the inlet pipe can fill the vat 7 hours, while the outlet pipe can empty it in
raketka [301]
Lets say, for ease, that the vat can hold a total of 70 gallons (or whatever you would like to use.) Use whatever number you want, I just picked this because it gives us a lot of clean numbers. 

Now, if the inlet can fill it in 7 hours, that means that it is adding 10 gallons per hour. (70 gal/7 hours = 10 gal/hr)

For the outlet, use the same process, and you find that it drains the vat at 7 gallons per hour. 

So, if you subtract the outlet from the inlet, you get 10 - 7 = 3 gallons per hour added. 

Now just divide the size of the vat by that number, and you find your answer. 

70 gallons / 3 gallons per hour = 23 1/3 hours.

2(4x - 1) &lt; 4(3x+1), where x ∈ {set of all negative Integers}​
alexgriva [62]

\large\underline{\sf{Solution-}}

Given inequation:

\sf 2(4x-1)

\sf\longmapsto 8x-2

\sf\longmapsto 8x-2-4

\sf\longmapsto 8x-6

\sf\longmapsto 8x-6-8x

\sf\longmapsto -6

\sf\longmapsto 4x>-6

\sf\longmapsto \dfrac{4x}{4}>\dfrac{-6}{4}

\sf\longmapsto x >-1\dfrac{1}{2}

Therefore:

\sf\longmapsto\boxed{ x=\{-1\}}\ \ Ans.
